The "Atom's Family" (to the tune of the Addam's Family song) -great for teaching the different parts of the Atom! The kids WILL sing it! This song originally only had 2 verses when it was first published and a student in my class wrote the verse.
Name songs are great because they make each child feel acknowledged and unique. By clapping name songs the children are learning how many beats or syllables are in their name. I would recommend to anyone who is leading group time.
